Dozens of elephants and rafts have been deployed to rescue almost 500 people trapped by floods in a popular resort in southern Nepal, officials say.
The country's home ministry said on Sunday that the death toll had risen to 49, with 17 people injured and thousands left homeless.
Seventeen bodies have been recovered from the accident site in the Himalayan state, said Sandeep Kadam, a senior official at the scene.
As many as 8,300 security personnel from Nepal Police, Armed Police Force and Nepal Army have already been mobilised in the rescue operation across the country.
But dozens were still missing somewhere at the bottom of the ravine, with soldiers and rescuers clawing through the mud and rock to reach them.
The Meteorological Forecasting Division has forecast moderate to heavy rains to continue across the country for the next few days.
Heavy rains have lashed Nepal for the last three days causing flooding and landslides.
Following the rescue operation, over 200 people from Narainapur, Holiya, Phattepur, Tikulipur, Bairiya Sikta among other places of Banke district were rescued to safer zones.
According to the Ministry of Home Affairs, seven persons were killed in Sunsari district in southern Nepal.
More than 30 people were reported dead on Saturday.
Footage aired on Nepali TV showed villagers wading through waist-high water with their belongings and using boats to reach higher ground.
Prime Minister Sher Bahadur Deuba addressed the nation on Saturday evening and announced relief to the victims.
A hotel owner in Sauraha, 155km (96 miles) south-west of the capital, Kathmandu, said the elephants had been used to take the tourists to the nearest open road and airport.
